GAS OR QOMBUSTION ENGINE.

Specification of Letters Patent.

Application filed November 10, 1909. Serial No. 527,196.

To all whom it may concern:

Be it known that I, LYMAN WooDWoRTH, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented or discovered certain new and useful Improvements in Gas or Combustion Engines, of which the following is a specification.

My invention relates to internal-combustion heat motor engines, more commonly called gas, petroleum, or alcohol engines, in-

which any suitable fuel, such as hydrocarbon or carbonaceous material hydrated or not, in gaseous, liquid, or finely divided state, is ignited'by any suitable means such as compression, electricity, or a hot body, and burned with air, preferably compressed,

the heated air and products-of-combustion, constituting or serving as the working-fluid of the engine.

The object of my invention is to increase the efliciency and improve the fuel economy of internal-combustion engines.

My invention consists in certain improvements in the combustion-chambers, cylinders, cylinder-heads, and pistons of internal combustion engines and in certain combinations of parts yvlth suitable nickel-plated metallic sheets,plates, or linings secured in place by mechanical means upon the interior surfaces thereof, confining the hotworking-fluid of the engine, as will be more fully hereinafter described in connection with the' accompanying drawings.

Figure 1 shows a side elevation, partly in section, of a gas or oil engine containing or "embodying my improvements. Fig. 2 shows an end elevation, partly in section, of the engine shown in Fig. 1. Fig. 3 shows a cross-section A.A of the engine cylinder of Fig. 1. Fig. t. shows a longitudinal section of the combustion-chamber, cylinder, and piston, of a gasengine containing my improvements, together with means for water cooling the heat exposed parts, Fig. 5. shows an end elevation, partly in section, of

, the parts shown in Fig. 4. Fig; 6. shows a longitudinal section "of the cylinder, cylinder-heads, and piston of a double-acting gas engine with my improvements.

Referring to Figs. 1, 2, and 3, the waterjacketed cylinder 1 provided with the cylinder-head 1, admission valve 5, exhaust valve 6, and igniter 7, is mounted" upon the engine frame 4. The engine piston 3 bearpiston 7 'into the lined portion of the cylinder; but I suitably V tions, as

ing or running in the cylinder 1, is connected by rod 10 to the crank-shaft 11 mounted in suitable bearings 12, in the frame 1t. Upon the crank-shaft 11 is mounted the flywheel 15. The cam-shaft 18 is operated by the gear-wheels 1 6 and 17 so as to make one revolution to every two revolutions of the crank-shaft 11, and provided with suitable cams and connections for operating the admission valve 5, the igniter 7 and the exhaust valve 6, as is well understood in engines of the class described.

The compression or combustion space end of the cylinder 1 isfitted or combined with the nickel-plated metallic lining 20 made in length equal to the piston stroke more or less, and in inside diameter sufiiciently greater than the outside diameter of the piston 3, to be out of frictional contact therewith.

The piston 3 is combined with interior nickel-plated metallic plate 21, preferably secured by center bolt 28 and nut 29.

In some forms of my invention, the engine 3 is made so that it does not'extend prefer to make the piston 3 reach into the lined compression-space a length equal more or less, to one-third of the piston stroke.

"By means of the construction and. combination of parts above described, the hot working-fluid of the engine or motor is confined more or less completely by the 1n- --terior nickel-plated metallic surfaces 20-and 21 respectively.

Sufficient of an internal-combustion en gine is shown in Figs. 4 and 5-toillustrate the connection of my invention therewith. In this construction, the water-jacketed combustion-chamber 2 containing admission valve 5, exhaust valve 6 and igniter 7, and I attached to the cylinder 1, is combined with the nickel-plated metallic lining 20, made in length equal to the piston stroke more or less, and in bore sufficient. to clear the piston 8. The interior nickelplated metallic surfaces 20. are fixed to the head end of the combustion-chamber 2, preferably by bolt 26 and nut 27 The piston face 3 is recessed and combined with the nickel-plated metallic plate 21 so as to formschamber or passage 35 for and 66 for leading water thereto, and connections 61, 63, 65 and 67 for conducting water therefrom, as is readily seen. The terminal supply and exhaust connections 66 and 67 respectively, are preferably mounted The water-jacketed cylinder 1 with operative inlet valves- 5 igniters 7, and outlet valves 6, has its ends fitted with the waterjacketed heads 1 combined with the interior nickel-plated metallic plates 20 suitably attached thereto as by interlocking screw threaded portions 24. The water cooled piston 3 mounted on the hollow piston-rod 3, is combined on its working-faces with the i v nickel-plated'metallic plates or sheets 21 secured in place by suitable means such as engaging screw threads 25. exposed parts have appropriate connections for supply of cooling fluid" or water, not

shown, as is well known and requires no detailed description. The said interior surfaces 20, 21 and 21, 20 respectively serve to confine the hot working-fluid of the engine.

It is obvious that my improvements apply to combustion-chambers and pistons in gas engines of other forms and figures than those shown, and that the valve ports, igniters, and the like, might be otherwise arranged; but the simple forms shown I deem best. In my invention, the interior nickelplated metallic plates and linings may be formed of any suitable metal and nickelplated in any suitable manner. In case the said plates or linings are formed of iron steel, or copper, they may be nickel-plate in asuitable bath of nickel salts, employing nickel anodes, and a suitable current of electricity, the nickel-plated surfaces being then polished or buffed in the usual and well The several heat v combination with witnesses.

known manner, so that the exposed surfaces present a smooth bright aspect.

The cylindrical lining 20, I prefer to form of cl0se grained cast-iron, the inside cylindrical surfaces bein heavily nickelplated and highly polishe The interior plates 20 and 21 may be formed of steel, cast-iron or copper, prefer- ,ably heavily nlckel-plated and highly polished upon the surfaces thereof that are to be exposedto the hot working-fluid 0f the engine.

The functions of the above described linin'gs are to resist corrosion, facilitate cleaning, and promote thermo-dynamic' efficiency of the engine.

Having described my invention, I claim:

1. In an internal-combustion engine, the combination with the combustion-chamber of suitable nickel-plated metallic plates or linings secured in placeby mechanical means upon the interior thereof, and with suitable means for cooling said interior parts, substantially as shown and described.

2. In an internal-combustion engine, the combination with the cylinder of suitable nickel-plated metallic plates or linings secured in place by' mechanical means upon the interior thereof, and with suitable means for cooling said interior parts, substantially as shown and described.

3. In an internal-combustion engine, the combination with the cylinder-head of suitable nickel-plated metallic plates or sheets secured in placeby'inechanical means upon the interior faces thereof. and with suitable means for cooling said plates or sheets, substantially as shown and described.

4. In an. internal-combustion engine, the the piston of suitable nickel-plated metallic platesor sheets secured in place by mechanical means upon the face or faces thereof, and with suitable means for cooling said plates or sheets, substantially as shown and described. 6

In testimony whereof I have signed" this specification in presence of two subscribing LYMAN WOODWORTH.
